Application May 12, 1948, Serial No. 26,502

2 Claims. (01. 91-50) My invention relates to improvements in apparatus for gumming bands such as are used in packaging operations, as for example, bands which are used in the bundling of stacks of paper, cards, or envelopes, or bands which are used in the packaging of mens shirts in a laundry.

In the performance of such various packaging operations as itemized above, speed is of the essence in order to insure quantity production. For example, in a plant producing envelopes, a machine might produce as many as 8 bundles or stacks of envelopes per minute, each stack containing 25 envelopes and each of which bundles or stacks must be banded in the well known manner. A person banding envelopes previously folded might be able to produce as many as 12 stacks a minute. By the device of my invention, it is possible to gum and to lift for operational use as many as 50 bands per minute.

It is the principal object of the device of my invention to provide a novel and improved means whereby the banding operation referred to above may be facilitated and the production of the finished product may be expedited.

Other prime objects of my invention include, first, the provision of a simplified construction of an apparatus for gumming bands, second, the securement of a higher degree of accuracy in the performance of work accomplished therewith than has heretofore been possible, third, the attainment of a higher degree of speed of construction of the device due to its simplification in construction and its unique composition of parts, fourth, the attainment of a flexibility or a capability of adjustment by which a large variety of work can be produced by means of the same device, fifth, the achievement of a greater ease in adjustment and repairs, sixth, the provision of an improved gumming device which may be made more economically and with fewer operations in the manufacture of its parts,

as well as in the assembly of the same, than The existing practice in the trade is to gum the labels in advance and to moisten them as they become ready for use. Devices of this general type heretofore known all have the common objective that a separate and distinct moistening operation is required. This causes additional effort and accordingly, I have devised a novel means whereby such difficulties and objections are overcome. I accomplish this by the provision of a device which obviates the need for a separate moistening operation.

With the foregoing and various other novel features and advantages and other objects of my invention as will become more apparent as the description proceeds, the invention con sists in certain novel features of construction and in the combination and arrangement of parts as will be hereinafter more particularly pointed out in the claims hereunto annexed and more fully described and referred to in connection with the accompanying drawings wherein:

Fig. 1 is a plan view of the device of my invention Fig. 2 is a side elevational view of the device of my invention with certain parts broken away for purposes of clarity Fig. 3 is side elevational view of the carrier of my device, and

Fig. 4 is a plan view of one of the band members as used in the device of my invention.

Referring now to the drawings more in detail, the invention will be fully described.

A support member is provided which consists of a pair of spaced side walls In and ID.

A carrier member comprising a base I2 is slidable into and out of relationship with and between the side walls It) and I0 and carries thereon a plurality of upwardly extending positioning members M which are adjustable and movable toward and away from the center of the base I2 by means of screws l6 which pass through elongated slots [8 in said members Hi substantially as shown in Fig. 1.

That is to say, a stack of bands or paper strips B, placed upon the base i2 may be snugly embraced on the sides thereof, and, as is shown in Fig. 2 on one end thereof as well, or, as is shown in Fig. 3 on both ends thereof as well, so that the bands are held in tight fitting relationship on their sides and may be removed only by lifting the same upwardly above and beyond the positioning members.

The width of the stack receiving means provided by the cooperative action of the members l2 and I4 is obviously variable by the adjustable movements recited above so as to fit the 3 requirements of the particular width of band being used. Thus, one device may be used for a variety of purposes in which a variety of widths of bands may be employed.

Also carried on the base member [2 is a glue pot which comprises side Walls 22 and end walls 24 joined together and fitted to the member l2 by any conventional means so as to provide a container for receiving a supply of glue G.

The glue pot is positioned relative to the base 12 so that when the carrier member is in operating relationship with the support member, the

to turn loosely and it has mounted thereon at a point intermediate its ends a roller 32 which is of such diameter that its lowermost portion extends downwardly into the glue pot substantially as shown in Fig. 2 and in the process picks up upon its surface a coating of the glue.

A doctor 36 is mounted upon a shaft 36 which extends between and is journalled to the side,- walls 10 and iii-in the well known manner. I adjusting means is provided on the doctor blade comprising a bracket 31 fixed to one of the side walls l0 and extending inwardly and above the member 34 and having at its inner end an adjusting nut 38 adapted to be moved downwardly against the member 34 so as to urge the free end portion thereof against the roller 32 for purposes regulating the thickness of the glue coating as the roller rotates in the direction indicated by the arrow at in Fig. 2. I

Fixed to the free extremity of the doctor 34 an apron 43 may be provided which is of such configuration as to embrace the sides of the roller 32 and to remove excess glue from the side walls thereof as the roller is rotated through. th glue pot and upwardly therefrom toward the; doctor. A coating of glue on the side walls of theroller being not onl unnecessary but also undesirable, the apron serves to remove the same andto assist the function of the doctor.

A pair of arms 53-each have a lower extremity pivotally journalled by journals 5| to .the side walls Ill and the upper extremities thereof are connected by a manually engageable cross member 52. A shaft 5 l has its extremities journalled into the arm members 55 and mounted thereon is a roller 56 preferably at a point intermediate the extremities of the shaft 54.

The roller 55 is of such diameter as to be con- I tiguous with the roller 32 so that the transfer of glue from the latter to the former is facilitated when the roller 56 is in the uppermost position shown in Fig. 2. When in this position, the roller 53 may be rotated in the direction indicated by the arrow b in Fig. 2 by the rotatingmovement of the contiguous roller 32.

The arms 53 are held in pivotal relationship with the side walls Ill, they being journalled thereto at 5|, and a spring means 53 is positioned between one of the side walls It and the member 52 so as to urge the combinationof 'thearrns 5B, cross member 52 and roller 56 up'wardly' and"for wardly at all times. However, being" in pivotal relationship, the arms 50 and rollenfifi'maybe' manually urged downwardlyan'd rearwardly by 4 means on said base for'positioninga stack of 4 the operators grasping of the member 52, whereupon the roller 58 moves out of its contiguous relationship with the roller 32 carrying with it upon its surface a coating of the glue received therefrom.

The roller 56 may be urged downwardly to a point where it overlies the stack of bands B substantially as indicated by the dot-dash lines in Fig; 2.- The roller 56 may be brought into contact with the uppermost band so as to deposit thereon a spot of glue as indicated by G in Fig. 4:.

Upon release of the member 52 by the operator, the roller moves upwardly and away from the stack of bands due to the spring action of the member 58 and as it does it carries with it the uppermost band, same being caused to adhere thereto by virtue of the gum spot G. As the uppermost band is lifted upwardly and is removed from the rest of the stack, same may be manually grasped and removed from its contact with the roller by a slight pulling action.

The shaft 30 may be driven by a moto (not shown) or by any other desired means.

The invention may beembodied in other specific forms without departing from the essential characteristics thereof. Hence, the present embodiments are therefore to be considered in all respects merely. as being illustrative and not as being restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all modifications and variations as fall withinthe meaning and purview and range of equivalency of the appended claims are therefore intended to be embraced therein.

What it is desired to claim and secure by Letters Patent of the United States is:
